Sex can cause psychological problems in women who engage in it when they're too young.
It won't hurt her physically most likely, but many studies have shown that women in their early teens get very little pleasure from sex compared to older women and are usually unable to orgasm.
If she doesn't think she's ready to have sex then she isn't.
I know a lot of people who became sexually active around that age, but it's only okay if both parties understand the need for safety and the risks involved and if both are really, truly prepared for it.
